France Applicatiorlin December 17 1930, sei-iai No. saisis' France December 20, 1929 2 Claims. l(Cl. 301-6) 'I'he present invention relates to wheels, adapted particularly for self-propelled vehicles andthe like and has for an object to provide a wheel with means for supporting the same from a brake drum l or other projection which is carried by the hub or other centrally located part upon which the wheel may be mounted or with which the wheel may turn so as to support the wheel against lateral and circumferential strains at a point distant radially from the hub.

Another feature of the present invention is tol provide a wheel structure adapted to engage the brake drum or web thereof in a line of contact concentric to the axis of the wheel and drum and which may co-operate with the usual wheel securing bolts or the like for placing the wheel under the desired tension against the brake drum or'its iiange for insuring the desired bearing of the Wheel against its support and thus distribute the lateral and circumferential stresses between the wheel and the supporting brake drum. A

Another feature of the present invention is to provide a wheel structure embodying the above characteristics and where when tension is placed upon the central portion of the wheel, the stresses setup in such portion of the wheel will be transferred to the brake drum or its equivalent sup-A port.

The invention also aims at the provision of certain features which may be embodied in all types )of wheels, and which is particularly adapted to wheels of the disc type.

With the foregoing and other objects in view,

the invention will be more fully describedhereinafter, and will be more particularly pointed out inthe claims appended hereto.

In the drawing, wherein like symbolsvrefer to like or corresponding parts throughout the sev-l eral views,

The ligure shows a transverse section taken through a disc wheel andv vits brake drum, the section being taken along the axis of the same. l i

Referring now to the drawing, the wheel 10 is shown as of inne disc type and is provided with `a central opening l1 and a plurality of independent nut receiving sockets 12 stamped or otherwise suitably formed in the body of the wheel 10 `and in a circular row concentric to the opening 11, and with the pockets 12 spaced apart the desired distance to accommodate the desired number of fas' tening elements. 'I'he wheel 10 is adapted to be secured against *l @he outer side of the web or flange 13 of the brake drum 14, the latter having a hub 15 in the usual brake drum flange or web 13 is relatively heavy manner. The fastening devices may be of any desired type land in the present yinstance are shown in the form of threaded bolts 16 wlrich'pass through the drum flange 13 and through the adjacent pockets 12.

Each bolt l6 has on its inner end a clamping nut 17 disposed within the drum 14 and engaging against the inner side of the web 13 for co-action against a. fixed collar or washer 18 disposed upon the intermediate portion of the bolt 16 and coun- 65 tersunkin the outer face of the web 13 as shown. The outer end of the bolt 16 passes freely through the adjacent pocket 12 and carries a relatively large clamping nut 19 adapted lto seat in the pocket and bear against the side for binding the central portion of the wheel 10 against the brake drum.

outwardly of the circular row of pockets 12, and in register with the peripheral edge portion of ,the drum flange 13, the wheel body is provided with a transverse annular rim 20 presenting a bearing surface 21 which i's of annular formation "and which inclines radially inward toward the axis of the wheel 10 and is adapted to bear against the outer edge of the drum 14 where it mergesinto the flange 13 so that the rim 20 provides a bearing member or surface carried by the wheel adapted to engage the outer portion of the brake drum and support the outer portion of the wheel directly from the brake drum and relieve, toa

large extent, the central portion of the wheel against the supporting stresses imposed on the v'wheel 10.

The fastening devices 16 when drawn up are` adapted to bind the bearing surface 21 against 90 the brake drum or its web 13 so that the brake drum web 13 in eiect becomesthe major portion of the central part of the wheel and, as the and strong, the outer portion of the wheel is thus supported to a greater extent through the brake drum. y I

The wheel body 10 is provided with a rim 22 of any suitable construction adapted to carry the tire and the rim 22 may of course be given any from the central portion of the wheel to a large` extent and are carried directly through the relatively strong and rigid brake drum or its equivaient which is carried on the hub portion 15. The

walls thereof 7 suitable construction or configuration, and may be made in any desired number of parts to accqmlan extent suicient to engage the central wheel will also offer a greater resistance to lateral stresses than in wheels which are supported wholly and directly from the central portion of the wheel.

'I'he structure is such that the tension placed on the central portion of the wheel increases the binding action of the wheel against the brake drum at a point near the rim 22 so as to further insure a rigid support for the wheel.

It is also apparent that the wheel when positioned upon the hub may or may not have two points of contact with the hub, the bearing surface 21 being so offset toward the inner side of the wheel as to rst engage the supporting flange or Web 13 and the subsequent tightening of the central portion of the wheel may be carried out to portion against the hub or not as,desired. e

It is obvious that various changes and modifications may be made in the details of construction and design of the above spe ically-'deseribed embodiment of this invention from the spirit thereof, such chan es and modications being restricted only by th l scope of the l following claims:

What is claimed isz'- l. A vehicle wheel comprising a disk like body portion having an annular rib forming a radial seating fulcrum and inwardly'thereof a bolt circle having plural annular seating zones inwardly and outwardly of said bolt circle.

2. In a vehicle wheel of the demountable boited on'type, the combination of a brake drum andii a disc like wheel body including an annular rib seating uponl said brake drum and inwardly of said rib, a bolting on circle having annular seating zones inwardly and outwardly thereof.
